I've also had some questions about the "FS4" project of this page. I actually had good fortune to find and e-mail Mr Robert Stein. Although I cannot locate the e-mails, I recall mentioning two issues with the project. First issue is critical parts no longer available and no good subs. Second and much more important is that the synthisizer had some bad spurs. Not usable for TX and annoying on RX.

It's not ideal but will do until someone produces and sells better one. Thanks for the info!

Lotsa fun. 73, Bob K6GGO I think the discussion is now about the expanded "preselector" dial that came with the FS4. HR magazine had home brew FS4 in Aug 1972 issue. That article had a copy of the dial in print. That might be where you can pick off a high resolution image if you have an origial. I sold my incomplete set of HR mags when I purchased the entire PDF collection. The PDF of the page that the dial is on is not that great. OTOH you might be able to use it for a starting point to do image restoration and enhancement.
